Claims.

This invention relates to improvements in spring cushion construction.

The principal objects of this invention are:

First, to provide a spring cushion structure in which the springs aresupported to permit substantial individual yielding action to load andat the same time, transmit a substantial portion of the load to adjacentsprings and to provide an effective upholstering supporting surface. f

Second, to provide a structure having these ad vantages which iseconomical to produce, durable in use and substantially noiseless.

Third, to provide a structure having these advantages in which thesprings are substantially spaced preventing their clashing and alsoeconomizing on the number of springs required.

Further objects and advantages pertaining to the details and economiesof the invention will be apparent from the description to follow. Theinvention is further pointed out in the claims.

A structure which embodies the features of the invention is illustratedin the accompanying drawing, in which:

Fig. l is a fragmentary front perspective view of an automobile seatcushion embodying my invention.

Fig. 2 is a fragmentary plan view thereof with the upholstery removed,portions being con-' veniently illustrated.

Fig. 3 is an enlarged fragmentary plan view showing certain of thestructural features or details of my invention.

In the accompanying drawing I have illustrated an embodiment of myinvention in a rear seat automobile cushion. While my invention is welladapted for embodiment in cushions of substantial size, it will beunderstood that the size and shape may be greatly varied.

In the embodiment illustrated the body springs l are of the hourglasshelical coiled type. The bottom border frame 2 and the cross supports 3are of suitable structure or design to support the body springs.However, this bottom structure as far as details are concerned form nopart of my present invention. The top border frame designated generallyby the numeral 4 comprises a so-called extension front frame member 5,rear frame members 6 and end extension frame members I. These are ofknown design.

The springs l are arranged in longitudinal and transverse rows and maybe substantially spaced as illustrated. The front border springs aresecured to the front border f-rame member 5 by means of clips 8. The endborder springs are secured to the end border frame member by ent is:

similarclips 8. The rear border springs are secured t0 the rear borderframe member by wire clips 9. The springs of the intermediatelongitudinal rows have their top coils connected by the helical tiemembers l0. The transverse row of springs H adjacent the border springsat one end of the cushion are connected to the border springs by meansofthe crossed helical tie members 52. The springs are further connected bymeans of the Webs of fabric i3 which are of substantial width and areslidably rove zig-zag through the top coils of adjacent springs ofadjacent longitudinal rows. The ends of these webs are secured by meansof clips It to top coils of the end'row of border springs at one end ofthe structure and are connected at Hi to the springs of the row 5| whichare as stated connected by the crossed helicals to the end bordersprings at the other end of the cushion. This provides a very effectivesupport for the springs and one which permits. substantial individualspringing or yielding and at the same time the load is well distributedthroughout the springs adjacent the points or area of compression. -Thewebs and the helical tie members provide an effective up-' holsterysupporting surface.

Structures embodying my invention may be very economicall produced, bothin the number of springs used and in the assembly thereof. The

springs are effectively supported in spaced relation so there is nopossibility of their clashing with adjacent springs and they areeffectively supported in upright position.

I have not attempted to illustrate or describe various embodiments 0radaptations to different types of seat cushions and back cushions as itis believed that this disclosure will enable those skilled in the art toembody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Pat- In a spring structure the combination of a topborder frame, coiled body springs arranged in longitudinal andtransverse rows, the top coils of the border springs being secured tothe border frame, helical spring tie members connecting the top coils ofadjacent springs of the longitudinal rows, the top coils of one end rowof border springs being connected to the top coils of the adjacenttransverse row of springs by crossed helical tie members, and webs offabric of substantial width slidably rove zig-zag through the top coilsof adjacent springs of adjacent longitudinal rows and secured at oneend. to the 3 springs connected to the springs having the crossedhelical tie connection to the adjacent end border springs and at theirother ends to end border springs at the opposite end of the structure.

2. In a springstructure the combination of a top border frame, coiledbody springs arranged in longitudinal and transverse rows, the top coilsof the border springs being secured to the border frame, helical springtie members connecting the top coils of adjacent springs of thelongitudinal rows, and Webs of fabric of sub stantial width slidablyrove zig-zag through the top coils of adjacent springs of adjacentlongitudinal rows and secured at one end to springs having spring tieconnection to the adjacent end border springs and at their other ends toend border springs at the opposite end of the. structure.

3. In a spring structure the combination of a top border frame, coiledbody springs arranged in longitudinal and transverse aligned rows, thetop coils of the border springs being secured to the top frame, and Websof fabric of substantial Width slidably rove zig-zag through the topcoils of adjacent springs of adjacent rows and secured at one end toborder springs secured to the top frame and. at their other ends tosprings having resilient connections to the top border frame.

4. In a spring structure the combination of atop border frame, coiledbod springs arranged in rows. in at least one direction, resilientconnections for the top coils of the springs of the rows, the borderbody springs being secured to the frame, and Webs of fabric ofsubstantial Width rove zig-zag through top coils of the springs ofadjacent rows and secured at one end to springs secured to the top frameand at their other ends to springs resiliently connected to the topframe.

5. In a spring structure the combination of a top border frame, coiledbody springs arranged in rows, the top coils f the end springs of therows being secured to the top frame, and webs of fabric slidably rovezig-zag through the top coils of adjacent springs of adjacent rows andsecured at one end to end springs of the rows connected to the top frameand at their other ends to springs adjacent to and having resilientconnections to end springs at the other ends of the rows connected tothe top border frame.

6'. In a spring structure the combination of a top border framecomprising front, rear and end members, coiled body springs arranged. in

longitudinal rows, the top coils of front, rear and end border springsbeing secured to the front, rear and end members of the border framerespectively, resilient tie members connecting the top coils of adjacentsprings in the rows, and webs of fabric rove zig-zag through the topcoils of adjacent springs of adjacent rows and secured at one end tosprings connected, to one end member of the border frame and at theother end to springs having resilient tie connections to the bordersprings connected to the other end of the frame. 7

7. In a spring structure the combination of a top border framecomprising front, rear and end memberscoiled body springs arranged inlongitudinal rows, the top coils of the front, rear and end bordersprings being secured to the front, rear and end. members of the borderframe respectively, tie members connecting the top coils of adjacentsprings in the rows, and webs of fabric rove zig-zag through the topcoils of adjacent springs of adjacent rows.
